摘 要:本文介绍介质pH值、Cu2+,Fe2+,Fe3+离子、六偏磷酸钠、CMC、水玻璃、六偏磷酸钠与水玻璃混用、CMC与水玻璃混用等影响镍黄铁矿浮选的研究概况;介绍捕收剂异丙基黄药、戊基黄药、丁基黄药、丁基铵黑药和丁基黄药与丁基铵黑药混用等用于浮选镍黄铁矿的情况;讨论了试验结果和探讨了浮选作用机理。
Abstract: The paper gives an outline of results obtained in an investigation about how pH value, Cu2+, Fe2+and Fe3+ ions, (NaPO3)6, Na2SiO3, (NaPO3)6+Na2SiO3 CMC, CMC+Na2Si03, etc. affect the flotation of pentlandite. Some collectors such as sodium iso-propyl, sodium amyl and sodium butyl xanthates, ammonium-butyl aerofloat, and sodium butyl xauthate+ammonium-butyl aerofloat, etc are also used to float pentlandite. The results obtained are discussed and the flotation mechanism is studied.
